Answer:
D. Refrigerants
Explanation:
In the United States of America, the agency which was established by US Congress and saddled with the responsibility of overseeing all aspects of pollution, environmental clean up, pesticide use, contamination, and hazardous waste spills is the Environmental Protection Agency (EPA). Also, EPA research solutions, policy development, and enforcement of regulations through the resource Conservation and Recovery Act .
The Clean Air Act Amendments of 1990 prohibit service-related releases of all refrigerants such as R-12 and R-134a. This ban became effective on the 1st of January, 1993.
Refrigerants refers to any chemical substance that undergoes a phase change (liquid and gas) so as to enable the cooling and freezing of materials. They are typically used in air conditioners, refrigerators, water dispensers, etc.
The Clean Air Act Amendments of 1990 prohibit service-related releases of all refrigerants. The correct option is D.
Thus, The Environmental Protection Agency (EPA), which was formed by US Congress, is the organization tasked with regulating all facets of pollution, environmental cleanup, pesticide use, contamination, and hazardous material spills.
All refrigerants, including R-12 and R-134a, are forbidden from being released during service under the Clean Air Act Amendments of 1990. On January 1st, 1993, this ban came into force.
Any chemical compound that transforms into a different phase (liquid or gas) to allow for the cooling or freezing of items is referred to as a refrigerant. They are frequently found in refrigerators, water dispensers, air conditioners, and other appliances.
Thus, The Clean Air Act Amendments of 1990 prohibit service-related releases of all refrigerants. The correct option is D.

Answer: Character reference is the tool usually followed in the business world.It is defined as the recommendation that is provided by organization employee that has a relation with the candidate(individual) outside of the work. This also known as the personal reference. The candidate can be friend family or any other known person whose reference is being given.

Answer:
bill = 47.28
tip = bill * 0.15
total_pay = bill + tip
each_share = total_pay / 2
print("Each person needs to pay: " + str(each_share))
Explanation:
*The code is in Python.
Set the bill
Calculate the tip, multiply the bill by 0.15
Calculate the total_pay, add bill and tip
Calculate each friend's share, divide the total_pay by 2. Then, print it in required format.
Answer: All of the above

Explanation:
Top-down design allows a programmer to take a complex idea, break it down into high-level tasks which can be further broken down into more detailed sub-tasks (Evans, Martin, & Poatsy, 2018). The larger a program gets, the more important it is to have a clear design. It is easier to fix an error during the design phase than the coding phase. If the design is flawed, a programmer can end up having to delete or rewrite large portions of code. Reworking large portions of a design is preferable to rewriting large portions of code. Even small programs can become overwhelming with a number of tasks to perform. Hierarchy Chart (hierarchical diagram) shows the breakdown of a system to its lowest manageable parts. It is a top-down modular design tool, constructed of rectangles (that represents the different modules in a system) and lines that connect them. The lines explain the connection and/or ownership between the different modules among the system just like in an organizational chart. main purpose is to describe the structure and hierarchy of an entity. This entity could be a strategy, event, software program, and so on. The hierarchy chart is suitable in any situation that aims to present the organized structure of a material or an abstract entity.
